Patented Dec. 10, 1929 UNITED STATES PAUL scnunnnrmor AUGSBURG, GERMANY TRUCK FOR REMOVING- HOUSE REFUSE Application filed ,May 31,1927, Serial No. 195,418, and in Germany October 21, 1926.

This invention relates to a motor driven vehicle for heapable goods, specially for the removing of house refuse, and it has for its opject to bring the heapable material to the front end which has been filled in at the rear end of a drum-shaped. receptacle until the drum is full, and to discharge the material from the rear end without tipping of the receptacle.

The invention consists essentially in that the drum is rotatably mounted on the vehicle and has helically extending plates which subdivide the total inner space of the drum in the longitudinal direction into helically extend ing compartments so that, when said drum is being revolved in the one direction, the material charged at the rear end is conveyed to the front end of the drum without being comm. pressed, said material, whewthedrulh is revolved in the opposite direction, being conveyed to the rear end anddischarged. An embodiment of the'invention is shown, by way of example, in the accompanying drawing, in which: Fig. 1 shows a longitudinal section through v the center of the motor driven vehicle which is partly shown in side elevation.

Fig. 2 isa rear end elevation. Fig. 3 shows the rear open end of the drum. In the frame of a motor driven vehicle a drum-shaped receptacle 1v for the heapable material is rotatably mounted. The drum 1 is closed at the front end by a bottom plate 2 and open at the rear end. On the inner surface of the drum plates 5 of sheet' metal are fixed which extend in helical shape from the rear end to the front end of the drum and in radial direction also to a central shaft 3.

The sheet metal plates 5 which may be arranged in several threads of screws are fixed at the outer edges to the wall of the drum and at the inner edges to the shaft 3, for instance by welding. Fig. 1 shows how the edges of two sheet iron plates extend, the edges of two other sheet metal plates being merely indicated. The total inner space of the drum 1 is subdivided by these sheet iron plates or partitions 5 into helically extending compart inents, as shown inFig. 3. Heapable material charged into the drum at the rear end of the titions,

same will travel towards the front end when said drum is revolving in clock-wise direction, but it will travel from the front end to the rear end of the drum when said drum is revolving in anti-clockwise direction so that the material isvdischarged at the rear end. As the drumis rotated with the helical parthese partitions cannot act like. a con-. veylng worm, so that the heapable material at the'filling of the drum will not be com-- 0 pressed when travelling towards the front end of the drum, the material being continually thrown about and loosened. in moving {.in forward direction. This effect is-specially favorable for removing house refuse as this house refuse contains irregular and unwieldy pieces, the conveying of the material requiring very little driving power. This is an essential difference from the known devices of this type, specially from those in which a conveying Worm is arranged and the receptacle is tippable. y

The drum 1 is driven from the motor 7 of the vehicle through the intermediary of a' change gear 6 and of a toothed crown 4 on the front end 2 of the drum. The change gear can be adjusted by means of a hand lever 8 and of a connecting rod 9 for right hand or left hand rotation. For charging the material into the drum, said drum is rotated in the one direction and rotated in the opposite direction for emptying. The rear open end of drum 1 is closed by a lid 10. A' horse-shoe shaped element which is fixed on the frame and encloses the drum, said horse-shoe shaped .35 element being formed by two U-irons 11 and 12, carries at the top end a section of a disk 13 and the lid 10 is hingedly connected to this section 13 by means of hinges 14. The lid bears onto the rear rim of the drum when itis hanging down in vertical-position, said rear rim having a ring-shaped bearing surface 15 which moveswith friction overthe inner surface of the stationary lid when the drum is revolving. The lower end of the lid may be fixed to the vehicle frame by any convenient means. The'lid is not plane but bulged inwardly concentric to the center so that it forms a conical cavity 16 in the direction of the drum, said cavity extending into the drum. The concavity in the lid serves for the insertion of the dust-bins. The houserefuse is charged into the rotating drum through an aperture 17 in the lower part of the cavity of the lid, the dust bins being supported-by the inner end 18 of this cavity. The conveying plates 5 in the drum extend from the front to the rear end of the same and they are cut out around the conical cavity 16 of the lid so that only a tongue 19 remains at the end of each partition, said tongues extending into the space around said cavity. These tongues move along the conical portion 16 of the lid and push the house refuse into the helical compartments of the drum.

When the drum has to be emptied the lid must be lifted. The horse-shoe-shaped frame 1112, which carries the lid, carries also the bearing rollers 20. These rollers 20 are arranged in pairs, one at either side of the drum, each pair in a double fork-bearing oscillatable on a stud 21. Each pair of rollers 'runs thus securely on the drum and only one quarter of the total drum-pressure acts upon the rear bearing. A ring 22 rigid on the drum serves as running path for the rollers. The front end of the drum is j ournalled by means of a ball-shaped journal 23 of the shaft in a corresponding bearing bracket 24:. This journaling ensures the drum against axial displacement and prejudicial influences by edging of the bearings, which may happen when the vehicle is moving over irregular ground, owing to sudden braking or to shocks caused by any other reason.

I claim 1. A motor driven vehicle for heapable materialspecially of house refuse, comprising in combination a horizontal shaft, a drum closed at the front end and open at the rear end and rotatably mounted on said vehicle, a change-gear driven from the motor of the vehicle and serving'to rotate said'drum,and several helicalisheet iron plates fixed on the inner surface of said drum spaced at similar angular distance extending in longitudinal direction from the rear end to the front end of the drum and in radial direction to said shaft said plates forming longitudinally ex tending compartments for the heapable material which when said drum is rotating in clockwise direction travels through these compartments from-the rear to the front end' of the vehicle so that it bears against the rear open end of said drum.

2. motor driven vehicle for heapable material specially of house refuse, comprising in combination a horizontal shaft, a drum closed at the front end and open at the rear end and rotatably mounted on said vehicle, a change-gear driven from the motor of the the front end of the drum end when the drum vehicle and serving to rotate said drum, helical sheet iron plates fixed on the inner surface of said drum extending in longitudinal is rotating in anticlockwise direction from the front end to the rear end of the same, a frame-shaped element fixed on said vehicle and embracing said drum, a lid suspended in said frame-shaped element so that it bears against the rear open end of.said drum, a conical inwardly directed portion of said lid projecting into said drum and having a charging aperture in its lower portion, and a tongue at each end of each helical plate in said drum and extending into the space between said conical cavity of said lid and the. inner surface of the wall of said drum.

- 3. A motor driven vehicle for heapable material specially house refuse, comprising in combination a horizontal shaft, a drum closed at the front end and open at the rear end and rotatably mounted on said vehicle, a bearing bracket fixed on the front end ofthe vehicle, a ball-shaped journal at the front end of said drum and engaging with said bearing brackets, rollers at the rear end of the vehicle bearing against either side of said drum, a double-fork bearing for each pair of rollers oscillatably mounted between the correspond ing rollers, a change-gear driven from the motor of the vehicle and serving to rotate said drum, helical sheet iron plates fixed on the inner surface of said drum extending in longitudinal direction from the rear end to the front end of the drum and in radial direction. to said shaft said plates forming longitudinally extending compartments for the heapable material which when said drum is rotating in clockwise direction travels from the rear to the front end of the drum end when the drum is rotating in anticlockwise direction from the front end to the rear end of the w same, a frame-shaped element fixed on said vehicle and embracing said drum, a lid suspended in said frame-shaped element so that it bears against the'rear open end of said drum, a conical inwardly directed portion of said lid projecting into said drum and having a charging aperture in its lower portion, and a tongue at each end of each helical plate in said drum and extending into the space between said conical cavity of said lid and the inner surface of the wall, of said drum.
